JOHN HANSON, OF HANSONVILLE, MINNESOTA.

INVALID-BED.

SPECIFICATION forming part of Letters Patent o. 669,217, dated. March 5,1901.

Application filed June 4, 1900.

To all? whom it may concern,.-

Be it known that I, JOHN HANSON, a citizen of the United States,residing at Hanson ville, in the county of Lincoln and State ofMinnesota, have invented certain new and useful Improvements in Invalid-Beds; an d I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved invalid-bed whichmay be easily adjusted by the occupant of the bed; and to this end theinvention consists of the novel devices and combinations of deviceshereinafter described, and defined in the claims.

The invention is illustrated in the accompanying drawings, wherein likecharacters indicate like parts throughout the several views.

Figure 1 is a perspective view showing theq bed constructed inaccordance with myinvention. Fig. 2 is a detail view in plan, showing aportion of the hanging couch-frame. Fig. 3 is a section on the line rc2003 of Fig. 2.4 Fig. 4 is a detail in bottom plan, showing a portion ofthe table or shelf with a paper-holder applied thereto. Fig. 5 is adetail in vertical section, showing the pawl-and-ratchet device forlocking the hoisting windlass-shaft. Fig. 6 is a detail viewapproximately on the section-line m6 c6 of Fig. 1, and Fig. 7 is adetail in horizontal section on the line :c7 007 of Fig. l.

In the preferred construction of my invention I employ a rectangularskeleton framework l 2, the sides of which are shown as connected bythree transverse windlass-shafts 3, 4, and 5 and also by a transverseguide-bar 6. The skeleton framework l 2 is applicable to a bedstead ofordinary construction, such as illustrated in the drawings, Fig. 1, bythe numeral 7. In the illustration given an ordinary wooden bedstead isshown,and the framework 1 2 is of wood, the vertical corner-posts lthereof being detachably securable at their lower ends to the foot andhead of the bedstead by means of screws or other suitable devices.Suspended, as presently noted, within the rectangular primary frameformed by the bedstead 7 is a rectangular elongated supplemental frame9, which serves as a frame for a vertically-adjustable couch or cot. Atone Serial No. 19,074. (No model.)

side the supplemental frame 9 is shown asprovided with a bearing-bracket10, in which is loosely journaled a short windlass-shaft 11, provided atits outer end with a ratchetwheel 12 and a perforated head 13, throughthe latter of which a sliding handpiece or doubleended crank l-i'ismounted t'o work. A springpressed retaining-pawl 15 on the bracket 10coperates with the ratchet-wheel 12 to prevent unwinding movementthereof, except when the said pawl is released by pressing on itstailpiece 1G. The lower ends of a pair of suspending cords orconnections 17 are secured to the windlass-shaft 1l and are run inopposite direct-ions over guide-sheaves 18, mounted on the ends of theframe 9. The cords or ropes 17 are then passed upward and are secured toand wound upon drum or sheave sections 19 and 2O on the windlassshaftsand 4, respectively. To each windlass-shaft 3 and 4 are attached theupper ends of a pair of suspending cords or ropes 21, the lower ends ofwhich are secured to the ends of the vertically-adjustable supplementalor couch frame 9.

Between the sides of the upper end portion of the frame 9 is pivoted at22 a frame-seetion 23, which is adapted to be thrown into differentinclined positions. To support the frame-section 23 at differentinclines, an upright bar 24 is pivotally secured at its lower end tothetransverse head-bar of the frame 9, as shown at 25, and is held upwardby engagement with the transverse bar of the said frame 23. At its upperend the bar 24 is provided with a guide-sheave 26, over which a cord orrope 27 is passed, said cord being permanently secured at one end, asshown, by an eye 28 to the frame 23 and detachably secured to a button29 on said frame 23 at its other end. By means of the cord or rope 27and the button 29 the frame-section 23 may be set and held in anyinclined position with re-A spect to the frame 9.

Canvas sheets 30 and 3l, respectively, are secured to the sides of theframes 9 and 23. To thus detachably secure the said sheets, the sides ofthe said frames 9 and 23 are formed with longitudinal tapered key-seats32, which are dovetailed on their inner edges, and for cooperation withthese key-seats long tapered Ioov keys 33, which are dovetailed on theirinner edges only, are provided. By means of the keys 33 the edges of thesheets 30and 3l are tightly pressed into the seats 32, and in virtue ot'the dovetailed sides of said seats and keys strains from weight on thesaid sheets will not. force the said keys out of theirseats, while, onthe other hand, the keys may be quite readily rolled out of their seats.by pulling upward on the outer edges of the said sheets. A

From the upper portion of the framework l 2 l .suspend an adjustableshelf` or table 34, which is preferably notched or cut out, as shown at35, so that said shelf may be closely adjusted to the occupant ot' thebed. At its ends the shelf 34 is pivoted by means of thumb-screws 36 tothe lower ends of a pair of arms 37, that are connected attheirintermediate portions by a transverse bar 33 and are provided a1their upper sections with long slots 39. Trunnions 40 of thewindlassshaft 5 Work Ih rough the slots 39 of the arms 37, and the endsof the said Windlass-shaft bear against the inner faces of the saidarms.

The horizontal frame-beams 2 are adapted lo be sprung slightly towardeach other to thereby frictionally clamp the arms 37 between their innerfaces and the ends of the said windlass shaft 5. To thus draw the beams2, I employ a toggle-link or connectn ing-rod 41, the ends of which areattached by hooks and eyes 42 or other suitable devices to the saidbeams 2. 'lhe intermediatejoint of the toggle-link 41 is connected toone end ot' a cord or rope 43, which passes through a suitableperforation in the bar 6, over a suitable guide 43' on the frame-beams2, and is adapted to be secured at its lower end to a button 44 on oneof the vertical posts 1. By drawing on the cord 43 the beams 2 are drawninward, due to the buckling action of the toggle-link 4l, so that thearms 37 may be frictionally set and held in any desired position.

To raise and lower the arms 37, the windlass-shaft 5 is connected lbyapair of cords 45 to the tie-bar 3S, and the said windlass-sha-ft isprovided with a third cord or connection 46, which is wound onv theWindlass-shaft 5 in a reverse direction from the cords 45 and isdetachably securable to a button 47 on said bar 38.

To move the arms 37 pivotally, one end ota cord or rope 48 is connectedto the bar 3S and is passed through a guide eye or perforation in thebar 6, thence through a suitable guide 48 on the beams 2, and issecurable at its lower end to a button 49 on one of the posts 1.

In Fig. 4 I have indicated a device in the nature of an attachment tothe table or shelf 34 for holding a newspaper or book in a position overthe invalid or occupant of the bed, so that it may be easily readWithout requiring the invalid to support or hold the said paper or book.Of the parts of this holder 50 indicates a light metal bar pivoted tothe free ends of a pair of links 51, which in turn are pivoted at theirinner ends to the under side of the table or shelf 34.

52 indicates a pivoted retaining-arm which is applied to the under sideof the shelf 34.

The character a' indicates a newspaper held by the device justdescribed. To thus hold the paper, it is folded over the bar 50 and issupported and held by the pivoted arm 52. A newspaper held as abovedescribed may be read on both sides simply by turning the shelf 34upside down on its pivots 36 after one side of the paper is read orafter the column is read to the folding-line of the paper. By tighteningthe thumb-screws 3o' Ihe shelf 34 may be frictioually held in anydesired adjustment with respect to the arms 37. By moving the parts 51and 52 pivotally the device may be adjusted to a paper or to a book ofalmost any size.

A person lying or reclining on the bed may adj ust the table or shelf 34int-o any desired position by manipulations already described and mayalso raise or lower the frame-section 23, as he may desire. Furthermore,he may by the handpiece 14 and windlass-shaft 11 raise and lower theframe 9 as an entirety. When the frame 9 is quite low down, it isnecessary to slide the handpiece 14 from end to end through the head 13in order to give clearance between the same and the side rails ofthe bed7. The vertically-adjustable frame and its sheets 30 and 3l are alsoserviceable where an ordinary spring and mattress are employed, as theyserve to raise the patient above the mattress, thereby permitting thebed to be made and the bedclothes to be changed when desired.

When the frame-section 23,With its canvas 31, is turned upward nearlyinto a vertical position, it may be used as a back, against which theinvalid may sit, and the frame made up of the arms 37 and table 34may beadjusted toward the same, so that the persons body below the arms ts inthe cut-away portion 35, and the body is thus supported at both sidesand at the back and at the front.

It will of course be understood that the invention above described iscapable of considerable modification in its details of construction andarrangement of parts.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is as follows:

1. The combination with a bedstead, of a framework extending above thesame, and provided with Windlass-shafts, of a supplemental frame,flexible connections suspending said supplemental frame from said Wind-1ass-shafts,and means for operating said windlass-shafts, comprising aiiexible connection and a Windlass mounted on said supplemental frame,substantially as described.
